Specification of Letters Patent.

Patented Nov. 5, 1907.

' Application filed May 16. 1907- Serial No. 374,066.

To all whom'it may Be it known that I, LEON F. Hmsnya resident of York, county of York, and State of Pennsylvania, have invented a .new and useful Improvement in Cover Lifters for Sheet-Metal Boxes, of 'which the following is a specification.

My invention belongs to that class ofcover lifting devices, in which the cover lifter is pivotally connected to the box, and is adapted to operate against the edge of the cover ior the purpose of lifting the same. Devices of this kind are not new.

My invention resides the particular construction of the device whereby it may be cheaply and expe-.

ditiously made, and readily applied to the'box.

The device is a key-like lever, consisting of three parts, a pivot, a finger piece by'which the device is turned and a shouldered portion between-the finger piece and pivot. All of these parts lie in the same plane, each on the prolongation of the other, and they are fashioned in one piece from sheet steel, being cut out and shaped at one operation. The pivot is quite short-just long enough to pass through the side of the box, and to have its inner end upset or headed up se as to hold the device in place. The shouldered portion extends under the edge of the box cover in position to lift it when the hey-like device is turned. And the finger piece, by which the turning movement is effected, protrudes as an extension from the outer edge of the shouldered portion.

The device can be'readily and quickly applied to the box, at one operation, the pivot serving as a punch to force its own way through the side of the box and its protruding inner end being then headed up during the same movement. The form and construction 'of the key-like lifter, permits of this way of applying and securing it in place. I

The device is intended moreparticularly for use on boxes for containing shoe blacking or polish, audit is in this connection that I shall describe it.

In the accompanying drawings to whichl shall now refer for a better understanding of my invention-Figure 1 is a view of the key-like cover lifter detached. Fig. 2 isa view showing the device as applied to a box, and in the position it occupies iulifting the cover.

' Fig. 3 is a vertical axial cross section of the box and cover with the latter down, the line of section being axially through the cover lifter.

The device is struck out in one iron: 9. fiat sheet of soft steel, and consists of the finger piece a, the pivot b and the intermediate shouldered strip or portion 0.

These parts, as before said are formed in one, and lie fiat in the same plane, one on the prolongation of the other, and the device as a whole is designed to stand at right angles with the wall of the box to which it is applied.

The box is lettered A and the co'verB. The device is applied to the box by passing the'pivot 6 through a hole in the side of the box, and then heading up or upsetting its inner end, this bringing the inner edge of the shouldered portion a up against the exterior of the sidewall of the box, the device being so located that the flat face of the shoulder portion lies just below and underneath the edge of the cover B when the latter is down. The edge of'the cover may be, and preferably is, slightly flared as at d, so that it will more surely be engaged by the shouldered portion 0 when the latter is turned on the pivot b as an axis. With the same end I in view the annular bead a: on the box, just below the point where the edge of the cover comes when closed, may be flattened, as at e, where it would otherwise meet the part cthus allowing the latter to get well underneath the edge of the cover. This flattening of the head can be effected by and during the operation of attaching the key to the box.

The operation of the device will be understood without further explanation, Its action in that regard is .riot unlike that of cover lifters of the pivoted lever type heretofore known. What is essentially novel If So faras I am aware, is its special form and construction and its application to the'box, as hereinbefore set forth.

I am aware thatit is not new with me to provide a .box with a lever-like cover lifter pivotally connected to the box and adapted to act against the edge of the cover to raise the same; and this Ido not claim.

What I do claim herein as new and desire to secure by Letters Patent is In combination with "the box and cover, the flat sheet metal key-like cover-lifter consisting of the finger piece a, the pivot b, and the intermediate shouldered strip 0 formed integral, the pivot b and finger piece a being 10- cated' upon, andprojecting from, opposite edges of the shouldered strip. 0, the device as a whole standing at right angles to the sideof the box and connected thereto by the pivot 11 in position to permit its shouldered portion 0 to act against the edge of the cover in order Lu lift the some, as hereinbefore shown and described.

In testimony whereof I aflix my signature in presence of two witnesses.
